Enzyme reactions

• Enzyme class: E.C.2.6.1.52 - phosphoserine transaminase.
• Reaction:
  1. O-phospho-L-serine + 2-oxoglutarate = 3-phosphooxypyruvate + L-glutamate
  2. 4-(phosphooxy)-L-threonine + 2-oxoglutarate = (R)-3-hydroxy-2-oxo-4- phosphooxybutanoate + L-glutamate
• Cofactor: Pyridoxal 5'-phosphate
